N567KXXX
1. GENERAL DESCRIPTION
The N567Kxxx is a powerful microcontroller (uC) dedicated to speech and melody synthesis
applications. With the help of the embedded 8-bit microprocessor & dedicated H/W, the N567Kxxx can
synthesize 6-channel speech+melody simultaneously.
The two channels of synthesized speech can be in different kinds of format, for example ADPCM
and MDPCM. The N567Kxxx can provide 6-channel high-quality wavetable melody, which can emulate
the characteristics of musical instruments, such as piano and violin. More colorful melody effects are
implemented in N567Kxxx series, such as modulation, vibrato, and pitch-bending etc. The output of
speech/melody channels are mixed together through the on-chip digital mixer to produce colorful
effects. With these hardware resources, the N567Kxxx is very suitable for high-quality and
sophisticated scenario applications.
The N567Kxxx provides at most 32 I/O pins, 384 bytes RAM , IR carrier, Serial Interface
Management (SIM), and more sophisticated applications, such as interactive toys, cartridge toys and
final count down function. 3-pair LED output pins with 64-level control means that numerous
combination of RGB colors may result in a versatility of colorful effects. In addition, N567Kxxx also
provides PWM mode audio output to save power during playback and Watch Dog Timer to prevent
latch-up situation occurring.
The N567Kxxx family contains several items with different playback duration as shown below:
(@4-bit NM4 algorithm, 6 KHz sampling rate)

Note: *: The duration time is based on 4-bit NM4 at 6 KHz sampling rate. The firmware library and timber library have
been excluded from user’s ROM space for the duration estimation.
Note: **: N567K121, K161, K201 are modified from N567K120, K160, K200 respectively to consist with OTP’s pad
sequence.
